CEILING HANGER Filed Sept. '27, 1943 2 Sheets-Sheet 2- Ill - INVENTORV dbhnEfi' chZe/nWe/rt Wm 2am )6.

ATI'D R N EYE on the support nut through the medium of a relatively'thin wide clamp nut 32 having interior threads engageable with the threads 22 on the support nut shank and screwed downwardly on the shank to assume clamping position with relation to the flange 25.

This construction provides a relatively simple hanger means which can be quickly mounted in position to support a suspended ceiling at a desired height. As will be readily apparent, the arm 16 may be directly attachedto flooring or the like or the hanger bracket may be supported by fastening elements extended through the aperof the bolt 43. As shown to advantage at Figures 11 and 12, the clip is mounted in operative position by sliding the same downwardly on the bolt 49 wherein the lips contact the chamfered sides 48 to spread the clip legs so that the-clip is lowered until the lips thereof are pressed downwardly on the ceiling 36. The nut 52 threadedly engaging the bolt 49 firmly maintains the clip in depressed position to clamp the margins of the ceiling against the flanges 39 of the support strip.

Thus, the flat supporting nuts 42 having sliding and thread engagement with the depending :hanger rods 11 serve to support the strips or tures IS in the rod and connected to the side face of a joist or the like.

therethrough and grooves 34 in the faces leading to the bore for the attachment of a wire or other lead elements 35 which is looped through the bore and grooves to lead the nut onto the rod.

In amodified form of the invention shown at Figures 8 to 14 inclusive, the suspended ceiling structure indicated at 36 is directly supported on longitudinal strips or moldings 3'? embodying a rectangular vertically elongated web 38 and laterally extending flanges 39 at th bottom of the web. At spaced intervals the web 38 is provided with vertical through bores embodying an upper part 39 and a bottom'part 40 of increased diameter. Medially of its top and bottom edges the web 38 of the strip is provided with transversely registering longitudinally elongated slots 46 opening into each bore 39 and of a size to receive therethrough a flat faced nut 52. The exterior of this nut is provided with a plurality of axially directed grooves '33 for convenient turning. while the center opening is formed to provide a pair of diametrically opposed quadrant shaped interiorly threaded sections 44 with notches 45 therebetween. This 'nut is designed for slidable and threaded engagement with a hanger rod I1 corresponding to that of the preferred form of the invention'and is releasably locked on the rod and the web of the strip 31 by means of U-shaped staple elements 46 driven into the opposite sides of the web and bent flat thereagainst for resilient engagement with the grooves 43 in the exterior of the nut.

The support strip 31' is additionally supported on each hanger rod'by one of the cap nuts 35 threaded on the lower end of the rod and fitted within the enlargedbore portion 40 as shown at Figure Intermediate its connections with the hanger' .rods I! the strip 31 is provided with a part having a transverse notch 41 and downwardly diverging chamfered faces 48 at the base of the notch and substantially above the bottom flanges 39. Through this notched portion is provided a vertical bore designed to slidably receive a vertical threaded bolt/49 having the head portion at the bottom fitted in a counterbore in the strip with the threaded portion of the bolt projecting above the chamfered base portion of the notch.

On the upwardly protruding portion of the bolt 49 is slidably fitted a spring clip 50 of essentially U-shaped formation having a center opening in the top transverse part slidably fitting over the bolt with the side legs normally assuming downwardly converging relation. At the lower free end each side leg of the clip is provided with an outwardly directed lip portion 5| while a square nut 52 is disposed to engage the threaded extension I order to facilitate the alignment of the support nut with the depending bracket rod H the bottom end portion of the rod may be provided with a bore 33 transversely l -bars 31 horizontally at a selected height, the

nut having an exterior diameter exceeding the thickness of th web 38 of the T-bar for suitable adjustment while the cap nut 3| thereon locks J the bar in position. 'The margins of the suspended ceiling sections 36 are disposed to overlap and rest on the bottom lateral flanges 33 of the bar and, at spaced intervals, are clamped thereon by the resilient clamping element or clips It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims. I

Having thus described my invention, I claim:

1. In a ceiling hanger, a flattened hanger rod having its opposed relatively narrow sides screw threaded, a nut having circumferentially spaced threaded portions interiorly thereof with notches therebetwe'ena'dapted for sliding and threaded engagement with said rod, a flange at the base of the nut for supporting a ceiling, and means for locking the ceiling on the flange.

2. A flattened hanger rod adapted to be supported in a depending position, the said rod having its opposed relatively narrow sides screw threaded, a nut having circumferentially spaced threaded portions interiorly thereof with notches therebetween adapted for sliding and threaded engagement with the rod, means held in adjusted position by the nut for supporting a ceiling, and means for locking the support means on the rod.

3. A flattened hanger rod adapted to be supported in a depending position, the said rod having its opposed relatively narrow side screw 4. In a ceiling hanger, a vertically supported threaded rod, a nut slidably and threadedly engageable with the rod, a flanged ceiling support bar having a vertical bore sli'dable over the rod and provided with slots in the side thereof to receive th nut, and means on the bar resiliently engageablewith the nut for ,releasably locking the latter inadjusted position. M 5. In a ceiling hanger, a vertically'supported threaded rod, a nut slidably and threadedlyfem gageabie with the rod, a flanged ceiling support bar having a vertical bore slidable over the rodand provided with slots in the side thereof to receive the nut, a, spring element secured to the side of the bar resiliently engageable with the exterior of the nut for releasably locking the same, I

and means slidably mounted on the bar for reresiliently clamping ceiling sections on the bar flanges,

6. In a ceiling hanger, a hanger rod having spaced screwthreaded portions with unthreaded portions therebetween, and spaced grooved weakened portions at intervals throughout its length to permit reducing the length of the rod to conform to the ceiling to be hung, a nut having circumferentially spaced internal threaded portions adapted for sliding and threaded engagement with the rod, a flange on the nut for supporting a ceiling, and a nut on the exterior of and means on the bar for resiliently clamping ceiling sections on the bar flanges.
